This may cause inaccuracy of the detector efficiency when measured using standard sources that are point-like sources emitting γ-rays isotropically. Obtaining a precise estimation of the full energy peak efficiency of the coaxial HPGe detector in the beam geometry for on-axis and off-axis measurements requires a Monte Carlo simulation. We performed Monte Carlo simulations that calculate the detector efficiency in the beam geometry. The effects of the off-axis distance and γ-ray beam size on the efficiency are quantitatively analyzed. We found that the intrinsic efficiency in the beam geometry is maximized when the beam hits the detector at specific off-axis distances. Our Monte Carlo calculations have been supported by nuclear resonance fluorescence experiments using laser Compton scattering γ-ray beams.","subitem_description_type":"Abstract"}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.radphyschem.2022.110241","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"M.Omer"}],"nameIdentifiers":[{"nameIdentifier":"1051420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshiyuki, Shizuma"}],"nameIdentifiers":[{"nameIdentifier":"1051421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryoichi, Hajima"}],"nameIdentifiers":[{"nameIdentifier":"1051422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M.Koizumi"}],"nameIdentifiers":[{"nameIdentifier":"1051423","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshiyuki, Shizuma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1051424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryoichi, Hajima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1051425","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Calculating off-axis efficiency of coaxial HPGe detectors by Monte Carlo simulation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Calculating off-axis efficiency of coaxial HPGe detectors by Monte Carlo simulation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-06-13"},"publish_date":"2022-06-13","publish_status":"0","recid":"86291","relation_version_is_last":true,"title":["Calculating off-axis efficiency of coaxial HPGe detectors by Monte Carlo simulation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:06:39.179370+00:00"}
